Hong Kong Water Network Protected by PermaNet SMS Leak Detector Network

Hong Kong was the first city in Asia to take advantage of the advanced leak detection capabilities of the Permalog noise loggers, with an initial deployment back in 1999. The loggers are placed on water pipes where they listen for the sound made by leaks, log the data and then transmit it for further analysis. This enables water companies to identify leak areas quickly and efficiently; saving time, money and water by enabling a rapid, accurately-targeted response to repair the issue.

Hong Kong Water Network Protected by PermaNet SMS Leak Detector Network

In Hong Kong, the Water Supplies Department (WSD) is in charge of maintaining the 7800km of underground water pipes in the city, and has a 15-year rehabilitation program costing billions of HK dollars to repair, upgrade and modernise the network. Their target is to reduce burst incidents from 2500/year in 2010 to 1000/year by 2015, and to decrease the leakage rate from 25% to 15%. Out of the 1100 cross-road pipes, around half are very old, and at increased risk of damage and disrepair.

When a pipe in the busy Wanchai district burst recently, the Hong Kong government identified a further 600 sites around the city where very old pipes run under busy streets, and deployed a new batch of Permalog+ noise loggers to watch for, identify and locate any leaks in these areas. 

Permalog technology is made and developed in the United Kingdom by Halma Water Management (HWM-Water Ltd), and the company’s distributor in Hong Kong is Allied Power Technology Ltd. Allied Power has supplied over 800 sets of Permalog+ units with SMS repeaters to the region, and also has a contract with the local government to analyse the data gathered from the system.

When deployed with SMS repeaters, the Permalog+ devices can function together as a nodal network, with all data being automatically transmitted back to a ‘home station’ – in this case Allied Power’s offices. Every morning, the company receives the leakage data for each of the install sites, and makes recommendations to the WSD based on this information.

Davis Li, Managing Director, said: “We manage a huge amount of data every day, which has to be organised and presented clearly. Because the noise loggers are on busy roads for this project, there is quite a lot of interference from road noise, which can complicate our job. The main challenge of this monitoring work is to localise a leak when a correlation is simply not possible. In these situations, we usually use the Permalogs’ Aqualog function to differentiate interference and help identify the leak location.”

When in Aqualog mode, a Permalog+ logger will measure and log acoustic data at pre-set intervals over an extended period of time, typically at night to minimise the traffic noise. This data can then be presented graphically so trends, anomalies and incidents can be clearly identified. This effectively displays whether or not the noise is caused by a leak, since any leak noise will be consistent.

The combination of the automated leakage data transmission for general leakage alerts, and in-depth on-site analysis with Aqualog, means that leaks can be quickly identified and problems repaired before they cause major disruption or damage to Hong Kong and its residents.

Optical Oxygen and pH Sensors for Monitoring of Food and Fermentation Processes

Novel fibre optic chemical sensors non-intrusive, provide real-time monitoring

Advances in high-performance sensor materials and optoelectronics have enabled novel optical sensors for use in applications in life sciences, pharmaceuticals, biotechnology, food and beverage processing and more. Compared with traditional electrochemical sensing techniques such as galvanic sensors, Ocean Optics optical sensors can be made in small and customizable form factors, allow non-intrusive measurements and do not consume the sample.

Ocean Optics’ oxygen and pH sensors are ideal for monitoring a wide range of samples, including viscous foods such as vegetable oils, salad dressing and peanut butter

Ocean Optics’ optical O2 and pH sensors are designed for accurate, real-time, in situ measurements in various media. The proprietary sensor coating materials do not consume the sample and can be applied to substrates such as probes, self-adhesive acrylic patches and microtiter wells. Coating options are available for general lab use, food processing lines and hydrocarbon-rich environments. Depending on the application, oxygen presence or pH can be visually determined by colour change with a handheld LED, or a fluorometer can be used to make exact measurements.

The principle of operation is to trap an oxygen-sensitive fluorophore or pH indicator dye in a sol-gel host matrix that can be applied to the tip of a fibre, an adhesive membrane such as a patch or a flat substrate such as a cuvette. The indicator materials change optical properties in response to specific analytes in their immediate environment and electronics then measure the response. For oxygen, the NeoFox Phase Fluorometer measures the partial pressure of dissolved or gaseous oxygen; for pH, a miniature fibre optic spectrometer measures the colorimetric (absorbance) response of the pH dye.

Ocean Optics optical oxygen and pH patches overcome the limitations of electrochemical-based oxygen and pH sensing. Such patches can be integrated easily within a small-scale biosystem such as a bioflask used for fermentation and provide continuous, non-intrusive monitoring of key system parameters. The ability to monitor dissolved oxygen and pH in real time without perturbing a sealed environment can lead to an improved understanding of the processes in the bioreactor and help to facilitate the development of new biological products and fermentation processes.

Elfab launches burst detection system for gas handling market

Elfab, the leading European manufacturer of rupture discs, has developed a burst detection system for the gas transportation industry. OE-Tel allows most customers with screw-fit rupture disc devices to benefit from fitting a simple, fail-safe burst detection system.

OE-Tel allows most customers with screw-fit rupture disc devices to benefit from fitting a simple, fail-safe burst detection system

Derived from Elfab’s unique, ATEX-approved Flo-Tel™+ burst detection system, launched in 2003, OE-Tel allows customers to identify when a disc has functioned. The unit offers all the benefits of Elfab’s family of magnetic burst detection systems and is available with the company’s screw-fit type of custom-engineered devices. These products are typically supplied in bonded brass, or electron beam units for more critical applications.

Gas transported in liquefied form by road tankers has to be kept under pressure. When a tanker arrives at a site, its pumping system is connected to the site’s storage vessel via a hose. Should the tanker try to pump too much gas, a rupture disc fitted to the storage vessel will burst, preventing the vessel from exploding.

When an overpressure event occurs, gas flow to the storage vessel needs to be shut off. This has traditionally required human intervention, which is problematic if the tanker driver is temporarily absent or the liquid gas has escaped and is obstructing access to the pump. OE-Tel ensures that the pumping system will automatically shut itself off as soon as the rupture disc bursts.

Unlike traditional membrane-type detectors, OE-Tel is fail-safe and non-invasive. The detection system is fitted to the vent side of the rupture disc and only operates when a disc has functioned, eliminating false alarms. The unit is currently undergoing ATEX approval for use in explosive atmospheres.

To assist with fitting and maintenance, Elfab offers Test-Tel™, which allows customers to check the detection system in situ without affecting the process.
